Phone-Verified Bookings
A one-time SMS code confirms every booking — fake bookings end.
Unverified bookings cost real money
- Fake names and ghost bookings block real slots
- No-shows hurt most on long sessions
- You can't reach the customer when plans change
- A name in a notebook is not a commitment
Verification built into booking
Before a slot is taken, the customer enters a one-time code sent to their phone by SMS. Every booking belongs to a real, reachable person.
- One-time SMS code - Sent at booking, single use, expires quickly.
- Real phone numbers - You can reach the customer when something changes.
- Commitment effect - A verified booking is far more likely to be honored.
- Zero friction - Just one code — instant access, nothing to set up.
How it works
Customer starts a booking
They pick a service, staff member, and time on your page, then enter their phone number to continue. There is no app to install and no account to create.
A one-time code is sent
ReservDM uses Twilio Verify to send a single-use code by SMS to that number. The code expires quickly, so it only works for this booking on this device.
Customer enters the code
They type the code into the booking page. Only when it matches is the slot held, so a mistyped or fake number can never block a real customer's spot.
Verified booking is confirmed
The appointment locks to a real, reachable phone. You can contact the customer if plans change, and automatic email reminders take the appointment from there.
